SPEED-INDICATOR v FOR SEPARATORS.

To allfwhomz'tmay concern: x

Be it known that I, EMIL HAUTALA, al citizen of the United States,l residing 'at Bruce Crossing, in the county of Ontonagonl and State of Michigan, have invented newand useful Improvementsin Speed-Indicators for Separators, of which the following is a specification. v

-This invention relates to speed indicators and is especially adapted for use in conjunction with 4cream separators, theobject in View being to provide a novel form'of indif cating means whereby the operator of .the cream separator may actuate the driving shaft of the separator at a speed governed by anotherA indicator actuated by clock mechanism.

In the operation of cream separators, to

obtain the best results, the driving shaft of vthe separator should be rotated at a certain number of revolutions per minute. It is a diiiicult thing to judge or estimate with any degree of accuracy, the speed at which the cream separator is manuallyy operated. By means of the improved indicating apparatus, the operator is enabled to judge accurately as to the proper speed of rotation of the separator during the entire operation thereof.

' With the above and other objects in view, the invention consists in the construction, combination and arrangement of parts, asI herein described, illustrated and claimed. In the accompanying drawings: Figure 1 is a fragmentary elevation of the cream separator, showing the speed indicator in its applied relation thereto.

Fig. 2 is an enlarged view of the indicator lookin@ toward the indicating or dial side .th ereo Fig. 3 is a vertical longitudinal section through the indicator.

Referrin to the drawings 1 designates the fly wheel o? a cream separator which is conventionally 4shown at A- and which is mounted on anoperating crank shaft 2 having an operating crank handle 3.

In carrying out the present invention, 1 provide a single trip 4: which is mounted on the rim of the fly wheel 1v adjacent to the. periphery thereof, `the purpose of which will presently appear.

The speed indicator comprises a housing4 or casing 5 of suitable size to contain clock mechanism 6, an arbor 7 of which is extended through the front wall 8 of the casing cream separator.

arbor or shaft 12 of which extends through the-front wall of the casing, where it has fast thereon an indicating hand 13 which sweeps around anotherdial .14 mounted or Specioation of Letters Patent.` Patented July 1, 1919. ,Appnmion uga Iu1y26,191s. serial mi. 246,900.

otherwise represented on the face plate of the casing.

Coperatively related to the wheel 1-1 is a reciprocatory thrust member or pawl 15, the upper extremity of which engages the teeth 11 and is yieldingly held in engagement therewithy by means of a spring 16, allowing the upper extremity of the member 15 to snap successively into engagement with the teeth of said wheel.v Backward movement of the wheel 11 is prevented by a spring pressed detent 17. yThe thrust member 15 extends downwardly through a guide 18 on the supporting post 19 of the casing 6, said Apost 19being secured by fastening means 20,

such as a screw or nut, to a fixed part of the machine, such as the machine frame. This enables the indicator to be removed from the cream separator and easily reapplied there- 'i The thrust 1member 15 is actuatedfby the trip 4 which is carried by the wheel 1 of the In each revolution of the wheel .1 and consequently the shaft 2 which is the driving shaft of the cream separator, an upward thrust is imparted to the member 15 which causes the wheelll to turn a Adistance equal to one tooth. The member l5 is retracted by means of the spring 16. When the indicating mechanism is not needed for immediate use, the thrust member 15 is raised and held out of the path of the trip tby means of a locking pin, bolt `or latch 21 which is adapted to extend under I a supporting shoulder 22 on the thrust'membe'r 15.

tion of the shaft 2 is 45`revolutions per minute, the clock mechanism is so desi ed and the parts of the mechanism thereo are so proportioned that the hand 9 will make one complete revolution or circuit of the dial in one minute and the dial' will be aduated from 0 to 45W The other will be graduated in the same way from 0 to 4:5, and therefore, the operator should operate the shaft 2 so that the hand 13 will sweep once around the dial for each coup v .100 Assuming that the proper speed of rota?A ial 14 revolutions per minute.

It will, of course, be understood that. if a lower or higher speed is required, the dial 1-1 and the gear 11 may be modified to Suit such change of speed.

I claim 1. In a speed indicator, the combination of an indicating hand mechanically driven at a predetermined speed, a dial in conjunction with which said indicating hand operates, a machine driving shaft, a second indicating hand actuated by a movable element of said machine, a second dial for thesecond named hand, the movementJ of said second named hand Ibeing manually Variable, the

means Afor actuating said second named hand, comprising a toothed Wheel fast on the arbor of the last named hand, a thrust member coperating with the teeth of said Wheel, a Wheel lforming an element of said machine,

' and a trip carried by the last named Wheel andeoperating with said thrust member.

2. In a speed indicator, the combination of an indicating hand, mechanically driven at a pre-determined speed, a dialin conjunction With which said indicating hand operates, a machine driving shaft, a second indicating hand actuated by a movable element of said machine, a second dial for the second named hand, the movement of said second named hand being manually variable, the means for actuating said second named hand comprising a toothed Wheel fast on the arbor of the last named hand, and a thrust member cooperating with the teeth of said wheeland actuated by a movable element of said machine.

In testimony whereof I athX my signature.
